In OntoUML output, label types are classified as aspects of the type they belong to, unless they are marked as a measure, have a value list, or are built up from other labels.

An aspect is something that can carry properties of its own, such as a condition or an attitude. A label type is a value: a number, a code, a name. The data type already recorded for the label shows which it is, so a numeric label can be presented as a measurable value and the remainder as plain data.

Expected: label types are classified from their data type, so that numeric labels appear as measurable values and the rest as data types.
